, 013 DETROIT, MICHIGAN, A CORPORATION REFRIGERATOR.

Application filed July 26, 1926. Serial No. 124,866.

This invention relates to refrigerators, and more particularly to supporting devices for anchoring brine tanks within the cooling chambers. a

Many refrigerators are constructed without provision-being made for securing a brine tank carrier. When no provision is-made for anchoring the brine tank carrier,'co nsiderable difliculty is encountered, because the installation must be made interiorly of the-cooling chamber, the carrier must be secured to support a considerable weight, and when the anchoring devices are extended through the cooling chamber lining care must be taken to prevent the passage of air through openings formed to receive the anchors. Under such circumstances, considerable time is therefore required to install a brine tank carrier, and generally, atbest, such installations are makeshift structures.

An object of my invention is to overcome the above difficulties by providing a refrigerator during its assembly with permanent anchors, to which the carrier of a-brine'tank can be secured, such anchors being designed to utilize a minimum space within the cooling chamber, so that such space is not restricted when the use of ice is desired.

A further object of my invention is to provide a refrigerator with anchoring devices to which a brine tank carrier can be quickly attached when it is desired to utilize a mechanical cooling apparatus. 7

These and other objects of the inventions will appear nore fully in the following description and will be set forth in the appended claims.

In the accompanying drawings,.Fig. 1 1s a front elevation of a refrigerator with a door opened and showing my invention installed in a coolingchamber; Fig. 2 is a vertical sectional view illustrating one of the anchoring devices attached to the refrigerator; and Fig. 3 is a similar vertical sectional view of a modified form of anchoring device.

Referring now to the drawings by characters of reference, 10 illustrates a refrigerator of conventional design, having a door 11 which closes the cooling chamber, and doors 12 and 13 which close food storing chambers. The inner top wall of the refrigerator casing comprises a layer of heat insulating material, such as cork, sections of which either ice or a brine tank can be used,

the brine tank, it will be understood, encloses an evaporator of a mechanical cooling apparatus. 1

Anchoring devices, for the attachmentof the brine tank preferably metal straps 16, are permanently secured to the supporting strips of the inner top wall of the refrigerator casing and extend interiorly of the lining 15. In the preferred form of one of such anchoring devices, I utilize an anchoring element in the form of a bolt having a threaded shank 17, which isinserted through aligned openings 18 and 19 formed respectively in the top of the lining l5 and the supporting members 14 of the refrigerator casing. Securing means are provided to fasten the anchor element and struction. One end of the anchor devices, the

bolt head, extends within the cooling chamber, and when not utilized to support a carrier for brine tanks they will not interfere with the capacity of the cooling chamber when'the use of ice is desired as the cooling agent. The. bolts are rigidly and tightly secured to the casing wall and will, therefore, provide strong anchors which will not deform the lining when a heavy brine tank is supported by a carrier which is secured to the bolts, and the arrangement of theanchor devices is such that no air will pass through the openings in the lining.

The end 23 of the bolt head 22 is flat and is provided with a central threaded aperture 24 to receive the threaded shank of a screw 25. The carrier is preferably made of a plu rality of metal straps 16, which are secured at their ends against the fiat ends 23 of the bolts by the screws 25 and such straps are arranged to carry the brine tank 2'3}- The readily shown in Fig. 3,

straps can be readily attached to the bolts and thus installation of the carrier requires a very short period of time.

In the'modified form of anchoring device I utilize internally threaded sleeves 30, having a flanged end 3111s the anchor clement, instead of the bolts pre-' sleeve 30 and the screw 32 in relative fixed relation. The carrier straps bear against the flanged end of the anchor elements 30 and are secured thereto by the screws 34, the shanks of which are screwed into the threaded interior of the anchor element 30.

It will be seen that with both forms of anchoring devices, I provide an anchor element which is fixed to the refrigerator casing and extends partially within the cooling chamber, so that a brine tank carrier can be aflixed thereto. This construction saves time in installation of the brine tank, and provides a rigid support which is connected so that the weight of the brine tank will not deform the cooling chamber lining.

Various changes can be made in the details of construction described herein, without departing from the spirit of my invention and the scope of the appended claims.

What I claim is:

1. A supporting device for anchoring a brine tank carrier within the cooling chamber-in a refrigerator casing comprising an anchor element extending through an opening in the wallet the refrigerator casing and the cooling chamber lining, said anchor element having a flangedend portion extending within the cooling chamber, means for secur- 'ing the flanged end of said anchor element tightly against the inner face of the cooling chamber linin said anchor element being supported solely by the refrigerator casing, and detachable means for securing said tank carrier to the flanged end of said anchor element.

2. supporting device for anchoring a brine tank carrier within the cooling chamber of a refrigerator comprising an anchor element extending through and entirely supported by a wall of the refrigerator casing. said anchor having a flanged portion within the cooling chamber adjacent the lining thereof, and means co-operating with said flanged portion for securing. said tank carrier to the flanged portion of said anchor.

3. A supporting device for anchoring a brine tank' carrier within the cooling chamber of a refrigerator comprising an anchor element extending through and entirely supported by a wall of the refrigerator casing, said anchor having a flanged portion within the cooling chamber, means for rigidly securing said anchor element to said casing, and means cooperating with said flanged portion for securing said tank carrier to the flanged end of said anchor.

In testimony whereof, I hereunto atlix my signature.

WALTER WHITTIER.
